Definitions

  • the invention relates to a device for ventilating a crankcase of an internal combustion engine according to the preamble of claim 1 .
  • a device of the generic kind is known from the practice of engine construction, in particular for automobiles.
  • the object of such a device consists in maintaining a negative pressure in the crankcase of the internal combustion engine, which is required for technical and legal reasons, by ventilating the crankcase.
  • Oil parts carried along in the ventilation gas of the crankcase are separated in an oil mist separator, and the separated oil is preferably recirculated to the lubrication oil circuit of the internal combustion engine.
  • the gas cleaned from oil gets into the suction tube of the internal combustion engine and subsequently undergoes the combustion taking place in the cylinder.
  • a device for the ventilation of a crankcase of an internal combustion engine, comprising a ventilation line, which leads from the crankcase to a suction tube of the internal combustion engine, and in the path of which an oil, mist separator is arranged.
  • a pump is arranged by means of which a negative pressure in the crankcase can be produced with respect to the ambient air pressure. This is intended to avoid that a pressure builds up in the crankcase which is too high, in particular, when the internal combustion engine is operated in its no-load range.
  • the invention is concerned with the problem to improve a generic device compared to the previously known prior art such that, in particular, a reduced required installation space can be achieved.
  • the invention is based on the general idea to embody ⁇ , for a device for the ventilation of a crankcase of an internal combustion engine comprising an oil mist separator and a pump downstream thereof for producing a negative pressure, the oil mist separator and the pump as connected modules.
  • a particular compact structure is achieved, which is of great advantage with respect to a consistently reduced installation space available in an engine compartment.
  • another line between oil mist separator and the pump is eliminated so that, on the one hand, the component variety is reduced, and, on the other hand, installation cost can be saved.
  • the pump is arranged downstream of the oil mist separator in a known manner. It is principally also thinkable that in such a module, a mounting space can be found which is advantageous for maintenance purposes so that a replacement of the oil mist separator or the maintenance of the pump is simpler, and hence more cost effective.
  • At least a portion of a stator of the pump is integrated in the oil mist separator.
  • the close engagement between pump and the oil mist separator is apparent, which is reflected in a very compact structure and hence in a small required installation space.
  • a simplified maintenance is possible, since a portion of the stator of the pump is formed at the same time as deflector wall for the oil mist separator, and, in case that this deflector wall is covered with an adequate non-woven fibre, or the like, allows a simplified access thereto.
  • the oil mist separator comprises an impactor having flow nozzles and a deflector wall opposite thereto.
  • Such oil mist separators formed as impactor are known for a long time from, for example, EP 1 068 890 B1, and ensure a reliable oil separation over a long operating time.
  • an additional oil mist pre-fractionator, or an additional oil mist post-fractionator is arranged upstream or downstream, respectively, of the oil mist separator.
  • a cyclone can be considered, which causes an additional cleaning of the blow-by gases containing oil mist.
  • Such a cyclone can also be used as post-separator.
  • a fan blade of the pump is arranged axially to the axis of the oil mist separator and rotates radially outside around the same.
  • Such an arrangement of the fan blade of the pump ensures a particularly compact structure, whereby the required installation space of the module formed by the oil mist separator and the pump can be reduced.
  • a part of the oil mist separator can be formed by parts of the stator of the pump, whereby the compactness of the module according to the invention can be additionally increased.
  • the oil mist separator and the pump preferably comprise a common housing, or are arranged in a common housing, respectively. Also this measure supports the compact structure of the module formed by the oil mist separator and the pump, and, in addition, eliminates the provision of a further housing, for example for the pump or the oil mist separator.
  • a common housing hence reduces the component variety, and helps reduce the manufacturing cost of the module.
  • FIG. 1 shows a cross section through a device according to the invention
  • FIG. 2 shows an illustration as in FIG. 1 but for a different embodiment.
  • FIG. 1 a device 1 according to the invention for the ventilation of a crankcase, which is not shown, of an internal combustion engine.
  • the device 1 is arranged here in a ventilation line, which leads from the crankcase to a suction line, or intake line, respectively, of the internal combustion engine, and comprises substantially an oil mist separator 2 , and a pump 3 arranged downstream for producing a negative pressure.
  • the pump 3 is arranged downstream of the oil mist separator 2 so that only cleaned blow-by gases get in contact with the fan wheel 4 of the pump 3 .
  • the pump 3 serves for producing a negative pressure which is intended to ensure that also in the no-load operation of the internal combustion engine, a gas pressure which is too high can be avoided, and the blow-by gases occurring in the crankcase are reliably sucked out.
  • the oil mist separator 2 and the pump 3 are embodied here as connected modules. This allows a particularly compact structure of the device 1 , and reduces its required installation space, which is of great advantage in particular with respect to the low installation space available in today's engine compartments.
  • the oil mist separator 2 comprises nozzles 5 , in particular flow nozzles or acceleration nozzles, respectively, which accelerate the gas flow flowing through the device 1 and lead it to a deflector wall 6 opposite of the nozzles 5 .
  • the deflector wall 6 is covered here, for example, with a fabric or a non-woven fibre, which again improves the absorption effect.
  • the oil collected at the deflector wall flows, according to FIGS. 1 and 2 , in direction of the gravity to a bottom 7 of the oil mist separator 2 , and from there to an oil discharge 8 , which is preferably connected with an oil reservoir which is not shown, so that the discharged oil can be recirculated again in a lubrication circuit.
  • the oil mist separator 2 is formed as impactor, wherein additionally an oil mist pre-fractionator or oil mist post-fractionator, respectively, can be provided.
  • an oil mist pre-fractionator which is arranged upstream of the impactor or the oil mist separator 2 , respectively, can be formed, for example, as a cyclone.
  • the pump is formed as an annular ducted fan, which, via its fan blades 9 , pushes cleaned blow-by gas towards an outlet 10 thereby producing a negative pressure in the oil mist separator 2 or in the crankcase located upstream thereof, respectively.
  • the pump according to the FIGS. 1 and 2 indicated by the reference number 3 represents here also the pump 3 installation space so that, for example, a support or drive, respectively, of the pump 3 can be placed therein.
  • stator 11 forms the deflector walls 6 .
  • an oil mist separator 2 is formed as a switchable oil mist separator, comprising a vacuum valve 12 , in particular a spring-loaded vacuum valve 12 , which, at a defined negative pressure, causes a redirection of the flow and releases further nozzles 5 ′.
  • the vacuum valve 12 is formed as a poppet valve. With open vacuum valve 12 , therefore, blow-by gas flows through the nozzles 5 as well as through the further nozzles 5 ′. Both nozzles 5 and 5 ′ have in common that they direct the accelerated blow-by gas flow onto the deflector wall 6 , thereby causing an oil mist separation thereon.
  • the fan blade 9 of the pump 3 is arranged coaxial to the axis 13 of the oil mist separator 2 and rotates radially outside around the same.
  • the fan blade 9 of the pump 3 according to FIG. 3 , is arranged offset in axial direction to the oil mist separator 2 , whereby the installation height of the variant of the device 1 shown in FIG. 2 increases slightly.
  • the oil mist separator 2 , as well as the pump 3 are arranged, according to FIG. 1 , in a common housing 14 so that compared to a separate formation of the two components, one housing can be saved. Unlike this, according to FIG.
  • the pump 3 and the deflector wall 6 of the oil mist separator 2 are arranged in a first housing part 14 ′, while the nozzles 5 of the oil mist separator 2 are arranged in a second housing part 14 ′′, which is connectable with the first housing part 14 ′.
  • This provides the advantage, that the individual housing parts 14 ′ and 14 ′′ allow a disassembling of the device 1 , which is particularly advantageous for maintenance.
  • the device 1 is characterized by a low installation height, for example 45 mm, and a small width, for example 90 mm.
  • the fan wheel 4 of the same including the fan blades 9 arranged radially outside thereon, are set in a rotation around the axis 13 , whereby blow-by gases are pushed towards the outlet 10 and are sucked in from an inlet 15 .
  • the blow-by gases containing oil mist enter the oil mist separator 2 via the inlet 15 , then they flow along the flow direction 16 up to the nozzle or the nozzles 5 , respectively, at which the blow-by gases are accelerated.
  • a deflector wall 6 is arranged, onto which the blow-by gases impinge, thereby releasing at least a large proportion of their oil carried along to the deflector wall 6 .
  • the blow-by gases flow further along the direction 16 towards the fan blade 9 , and from there, to the exit 10 .
  • the oil collected at the deflector wall 6 runs in direction of the gravity and drips onto the bottom 7 , which, at its lowest point, comprises the oil discharge 8 .
  • This oil discharge 8 is preferably connected with the oil reservoir and recirculates the separated oil to the oil circuit.
